In their report about Ben Affleck not being able to direct the pilot for The Middleman, it's said the reason is because of a scheduling conflict with Affleck portraying Batman. It's said regarding Batman Vs. Superman that "word is that production is not being delayed and the main players have been summoned to start work right away."

It's also said that Ben Affleck is involved with other commitments in the Spring as well.

This news might suggest that Ben Affleck either never got injured or the injury wasn't that bad (or that Affleck healed in time as some reports stated Affleck was involved in a skiing accident in December).

It's possible the news also supports rumors that Batman Vs. Superman and Justice League are to be filmed consecutively as a delay in the former would delay the latter.
